DS-CERAMIDE Y3S is one of the most purist ceramides containing stereochemical structure identical to those found in human skin. Ceramide 3 has been used as a highly functional cosmetic ingredient for maintaining skin moisture balance by repairing damaged skin lipid barrier.

DS-HYDROCERAMIDE 50S has Ceramide 3 as a main ingredient. Ceramide 3 is widely known as a fucntional ingredient for cosmetics. Not only does it reinforce the natural lipid barrier of dry and aging skin but it also shows an outstanding ability to maintain the moisture balance of skin. Ceramide 2 however exhibits very low solubility in water and oil, and even though it can be solubilized by a conventional emulsification method, some problems including coagulation, flocculation, coalescence, and creaming phenomena still occur due to its recrystallization behavior. Despite its high physiological efficacies, these problems make it difficult to apply ceramide 3 in cosmetic formulations. DS-HydroCeramide 50S was developed to solve these problems, and can be easily applied to any types of skin care and hair care products.

DS-CERAMIDE Y30 is high purity identical to those in natural skin, A major component in surface skin structure(Stratum corneum), Strengthen Skin’s natural barrier function, Retention of moisture content within skin, Rejuvenation and Anti-aging, Highly effective for Sensitive skin, Atopic dermatitis
